There are times in our daily lives where our emotions play a part in our decisions, our thought processes etc. Yet can emotions become too overwhelming that it works against our rational/ sane? In thinking this how powerful are our emotions? What about emotions barley playing a part in these decisions and day to day life? What do you guys think?

Believe it or not, most decisions you make are based not so much on logic and reason but how you feel about a circumstance. Even apathy is, at it's core, an emotional response. Rationality, logic, and all the other self-styled excuses we've created to justify certain actions are all well and good but little more than that. That's why most decisions made in one's lifetime are made based almost entirely on how you feel, not how you rationalize things.

Emotions are based in the lymbic system, which is the reptilian brain.

Emotions are instinctive. We require them to sense what is happening in a situation. A senseless person doesn't feel a situation's emotional characteristics, and that likely leads them into troublesome predicaments. Hence, the power of the emotions involved aren't felt where they really needed to be in order to constitute a socially acceptable situation.

Emotions can have power over reasoning, causing irrational behavior i.e. anger leading to workplace violence leading to disciplinary actions, such as supervisor/employee discussions and/or job suspension. Romantic love's emotions can make you perceive reality as something it is not, though you might argue that reality without romantic love is unrealistic. Instinctively, our inner primal creature doesn't fully trust the nature of dependency and instability in romantic love, since pair bonding for the purpose of procreation tends to be temporary, made more complex by controlled marriages, in which those involved in these relationships might secretly or outwardly desire separation legally, consensually, and with possible/likely acceptance by a juries of peers. Desire can play a role in emotional power, tempting the desiring person into the overindulgence of stimulating habits, such as drugs, sex, and constant, covetous, meddling, and destructive socialization.

Emotions are necessary, though control over them is required to keep civil order in all societies, not just those of humans. This cannot always be the case, in which situations arise where emotional control is not likely maintainable due to various environment and internal stressors. There is great power in the individual who demonstrates emotional control. It is something which can be called temperance, which lends dignity, and integrity, to the highly skilled practitioner.
